Study Endpoints

Primary Endpoints

Area Under the Plasma Concentration-Time Curve From Time Zero to the Time of the Last Quantifiable Concentration (AUClast) of Etrasimod
At pre-dose and 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

AUClast was calculated using linear/log trapezoidal method.

Area Under the Concentration-time Curve From Time Zero Extrapolated to Infinity (AUCinf) of Etrasimod
At pre-dose and 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

AUCinf was calculated as AUClast + (Clast\*/kel), where Clast is the predicted plasma concentration at the last quantifiable time point from the log-linear regression analysis, and kel is the terminal phase rate constant calculated by a linear regression of the loglinear concentration-time curve.

Maximum Observed Plasma Concentration (Cmax) for Etrasimod
At pre-dose and 1, 2, 4, 6, 8, 12, 24, 48, 72, 96, 120, 144, and 168 hours post-dose on Day 1 of each period

Secondary Endpoints

Change From Baseline in Heart Rate at 1, 2, 3, 4, 5, 6, 8 and 24 Hours on Day 1
Baseline, 1, 2, 3, 4, 5, 6, 8 and 24 hours post dose on Day 1
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
From start of study treatment up to 28-35 days after last dose of study treatment (maximum up to 72 days)
Number of Participants With Clinical Laboratory Abnormalities
Up to Day 45
